[Qemu-devel] Status of sun4u emulation?

[Markus Dahms]

Hi,

I'm curious about the status of the Sparc64/Sun4U emulation. I tried
to execute a little hello world program without success (output below).
The program runs fine on real hardware, the same little thing built for
sparc32 does what expected with qemu-sparc.
I'm also wondering why sparc64-softmmu is not build by default (not in
TARGET_DIRS).

Another sparc-related question: is there a way to press Stop-A in
system emulation mode? I even have a Stop key using a Sun Type 6 USB
keyboard on my PC, but that doesn't seem to be enough...

Thanks & Greetings,

        Markus
